1 第一個(gè)問題

執(zhí)行mvn clean deploy失敗，報(bào)錯(cuò)如下：

Caused by: org.apache.maven.plugin.MojoExecutionException: Failed to deploy artifacts: Could not transfer artifact com.cainiao:nballowance-client:jar:1.0.4-snapshot from/to releases (http://mvnrepo.xxx.com/mvn/releases): Failed to transfer file: http://mvnrepo.xxx.com/mvn/releases/com/cainiao/nballowance-client/1.0.4-snapshot/nballowance-client-1.0.4-snapshot.jar. Return code is: 401, ReasonPhrase: Unauthorized.        at org.apache.maven.plugin.deploy.DeployMojo.execute(DeployMojo.java:193)        at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134)        at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:207)pom.xml文件也是snapshot的（release權(quán)限控制，不能再本地deloy到中央倉(cāng)庫(kù)）
	<groupId>com.xxx</groupId>	<artifactId>nballowance-client</artifactId>	<packaging>jar</packaging>	<version>1.0.4-snapshot</version>
問題出在這里，version版本號(hào)snapshot是小寫的，改成大寫后OK。
2 第二個(gè)問題
Caused by: org.apache.maven.plugin.CompilationFailureException: Compilation failureUnable to locate the Javac Compiler in:  d:/jdk1.8.0_101/../lib/tools.jarPlease ensure you are using JDK 1.4 or above andnot a JRE (the com.sun.tools.javac.Main class is required).In most cases you can change the location of your Javainstallation by setting the JAVA_HOME environment variable.檢查 JAVA_HOME 符合預(yù)期
$ echo $JAVA_HOMED:/jdk1.8.0_101解決辦法
新建一個(gè)文件夾命名為lib，拷貝 tools.jar文件到新建的lib文件夾，把lib文件夾拷貝到和jdk1.8.0_101文件夾同級(jí)的目錄（D盤下）
然后執(zhí)行 mvn clean deploy 解決。
